Large clear-Pb mobile barrier consists of a large shatter-proof lead-plastic window that has been designed to block 90% of Tc-99m emissions, whilst maintaining visibility of the patient at all times. The lower panel has been lined with lead to give full body protection. The barrier is wide enough to shield up to two people at a time, whilst the easy-glide castors mean that the shield can be moved to the desired position wherever needed. The viewing panel is 24" x 36", whilst the lower panel is 34" high and 36" wide. The whole screen weighs 170lbs.
